In a new film, you can follow researchers and fish farmers as they hunt for infectious bacteria that make farmed salmon ill – so ill that the fish can die. Can we save them?

Highly pathogenic avian influenza has been detected in a one-year-old male polar bear and a walrus at the northern end of Spitsbergen. This is the first time this virus has been detected in a polar bear in Norway as well as a first for Europe for this species.

High mortality among cleaner fish in sea cages, combined with a variable ability to eat lice, has led researchers to conclude that the use of cleaner fish should be phased out within a few years. Animal welfare is too poor, a new review article shows.

TriNation is celebrating its 20th anniversary in Belfast on April 16th–17th. This initiative was established by researchers from Norway, Ireland, and Scotland to exchange experience on heart health challenges affecting salmonid fish.

Unfortunately, many rat poisons also end up in the diets of wild predators, as well as in the stomachs of dogs and cats, and in the environment. Research is now underway to identify rodenticides that are equally effective but break down quickly in the environment, thereby reducing their harmful effects on non-target animals.

New research reveals how dangerous variants of a little-known bacterium differ from harmless ones – and why certain variants in particular can make dogs ill.

As part of the Norway funded One Health project “Controlling zoonotic diseases and AMR in the milk value chain in Ethiopia, Malawi and Tanzania (OH Milk)”, a two-day stakeholder net-mapping workshop was held in early September 2025 in Addis Ababa, Ethiopia.

What if the answers to future health threats are already stored — frozen today?
The Norwegian Veterinary Institute uses one of Europe’s first fully automated biobank freezer systems within veterinary medicine.

A new study shows how stress affects the blood cells of farmed Atlantic salmon, reducing their ability to resist disease. The research also reveals how specific genes in the fish can act as early indicators of stress.

The Norwegian Veterinary Institute has played a key role in strengthening fish health and promoting sustainable aquaculture in Sub-Saharan Africa.
